[1] https://developer.arm.com/products/processors/cortex-r/cortex-r52 ChangeLog entry is as follows: *** gcc/ChangeLog *** 2017-07-14 Thomas Preud'homme * config/arm/arm-cpus.in (cortex-r52): Add new entry. (armv8-r): Set ARM Cortex-R52 as default CPU. * config/arm/arm-tables.opt: Regenerate. * config/arm/arm-tune.md: Regenerate. * config/arm/driver-arm.c (arm_cpu_table): Add entry for ARM Cortex-R52. * doc/invoke.texi: Mention -mtune=cortex-r52 and availability of fp.dp extension for -mcpu=cortex-r52. Tested by building an arm-none-eabi GCC cross-compiler targeting Cortex-R52 and building an hello world with it. Also checked that the .fpu option created by GCC for -mcpu=cortex-r52 and -mcpu=cortex-r52+nofp.dp is as expected (respectively .fpu neon-fp-armv8 and .fpu fpv5-sp-d16 Is this ok for trunk?
